text: Determination of porosity is one of the most important uses of neutron porosity log. Correction parameters for lithology, borehole parameters, and others are necessary for accurate porosity determination as follow:
  # Borehole size
  # Borehole salinity
  # Borehole temperature and pressure
  # Mud cake
  # Mud weight
  # Formation salinity
  # Tool standoff from borehole wall
